OT?: Sunset Zones

I am glad to see some favorable comments on the Sunset National Garden
Book zones. I think that using this reference will lead to fewer garden
failures, and thus less discouragement. The USDA Zones are too broad.
There is a lot of difference between Zone 7 Delaware, Zone 7 Tennessee,
Zone 7 Texas, and Zone 7 Washington. Sunset has at least TRIED to address
this.
Happy Gardening.
